Use of the Berg Balance Scale to Predict Independent Gait After Stroke: A Study of an Inpatient Population in Japan Hyuma Makizako, PhD, PT, Norihito Kabe, MSc, PT, Asami Takano, ST, Kanako Isobe, CW
Abstract Objective: To examine whether the Berg Balance Scale (BBS) score on admission and after 1 month can be used to predict the Functional Independence Measure (FIM) walking level 6 or 7 (modified independent and independent gait respectively) after 3 months and to determine the optimal BBS cut-off score for predicting independent gait among inpatients with first stroke in a rehabilitation facility. Design: Retrospective cohort study. Setting: Inpatient rehabilitation facility (Kaifukuki). Participants: Two hundred fifty-one consecutive patients with first stroke and nonindependent gait on admission. Outcome Measures: BBS on admission and after 1 month and FIM on admission and after 3 months. Results: Area under the receiver operating characteristic curves for predicting independent gait after 3 months were 0.81 (95% confidence interval [CI], 0.75-0.88) for BBS score on admission; the optimal cut-off score being 13 (63% sensitivity; 90% specificity). Achieving greater cut-off score on admission was significantly associated with subsequent independent gait (odds ratio, 9.7; 95% CI, 4.38-21.36; P < .001). A subanalysis of patients with poor balance on admission (BBS score
